I claim:

1. A container for a product processed therein, comprising a body, flanged end closures proportioned and dimensioned to be slidably frictionally telescoped upon the ends of the can body, thereby providing a hermetic seal, the flange on each end closure being provided with holes located intermediate the depth of the flange, the circumferential disposition of the holes in each flange being such as to provide a substantially uniform ingress and egress of the processing fluid when the holes are not covered by the container body.

2. A container for a food product to be processed therein, comprising a body, flanged end closures slidably frictionally telescoped upon the ends of the can body, thereby providing a hermeticseal when said ends are forced home, the flange on each end closure being provided with a plurality'of peripherally spaced apertures located intermediate the depth of the flange, the circumferential disposition of the apertures in each flange being such as to provide a substan tialiy uniform ingress and egress of the processing fluid uniformly through the contained product when the end closures are partially telescoped on the container body and the apertures are not covered by said body, said apertures being sealed by said container body when the end closures are in innermost position relative to said body.

3. A container for a food product processed therein, comprising a body having curled heads at its opposite ends, flanged end closures. each proportioned and dimensioned to be slidably frictionally telescoped upon the ends of the can body and each having a sealing compound ,therein, thereby cooperating with the closure flanges to provide a hermetic seal when said ends are forced home, the flange on each end closure being provided with peripherally spaced apertures located intermediate the depth of the flange, the circumferential disposition of the apertures in each 'slidably frictionally telescoped upon the ends of the can body, and a sealing compound in said channel, thereby cooperating with the closure flanges to provide a hermetic seal when said ends are forced home, the flange on each end closure being provided with peripherally spaced apertures located intermediate the depth of the flange, the circumferential disposition of the apertures in each flange being such as to provide a substantially uniform ingress and egress of the processing fluid uniformly through the contained product when the end closures are partially telescoped on the container body and the apertures are not covered by said body, said apertures being sealed by said container body when the end closures are in innermost position relative to said body.
